3 Monitoring Capacity This chapter includes: Topics: • • • • • • About monitoring system capacity Capacity data collection and retention periods Capacity forecasting and recommendations Capacity data locations in PowerStore Manager Start monitoring capacity usage Data Savings features About monitoring system capacity PowerStore provides various current usage, and historical metrics.
Historical capacity data collection and retention periods Historical capacity is displayed once data collection begins. One year of capacity usage data is displayed in the charts, and the data is retained for up to 2 years. Historical charts scroll automatically to the left when new data is available.
Capacity data locations in PowerStore Manager You can view capacity charts for PowerStore systems, and system resources from the PowerStore Manager Capacity cards and views in the following locations: Table 4. Capacity data locations For Access path Cluster Dashbaord > Capacity Virtual Machine Compute > Virtual Machine > [virtual machine] opens with capacity for the virtual machine displayed. NOTE: Only available with PowerStore X model appliances.
Data Savings features Data savings metrics are based on the automated inline data services that are provided with the PowerStore. The automated inline data services occur in the system before the data is written to the storage drives. The automated inline data services include: • • Data reduction, which consists of deduplication and compression. Thin provisioning, which enables multiple storage resources to subscribe to a common storage capacity.
While the system allocates only a portion of the physical capacity requested by each storage resource, it leaves the remaining storage available for other storage resources to use. The system reports the capacity savings gained from thin provisioning using the Thin Savings metric, which is calculated for volume families and file systems. A volume family consists of a volume and its associated thin clones and snapshots. Thin provisioning is always enabled.
